How does a robotic arm know where and how to move?<\/strong><\/p>

Every robot movement is created by combining the motion of multiple joints.<\/p>

Robotic arms use joint rotations and coordinate directions to position the end-effector accurately in 3D space.<\/p>

Understanding X, Y and Z movement<\/strong>, robot joints<\/strong>, gripper control<\/strong> and movement precision<\/strong> is the foundation of practical robot control.<\/p>

These concepts apply across medical, industrial, agricultural, logistics and service robotics.<\/p>

ROBOT CONTROL STARTS WITH THREE FUNDAMENTALS:<\/strong><\/p>

POSITION \u2192 ORIENTATION \u2192 PRECISION<\/strong><\/p>

In the following micro-lessons, you will make the same types of control decisions used when operating a robotic arm.<\/p>
